Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with accompanying drawings and examples.

[0019] like Figure 1~3 As shown, the present invention provides an integrated method of gangue transportation-crushing-filling in mines, which mainly includes: adjusting the fastening nut of the fixed rod of the telescopic frame and the nut of the bearing seat of the rear moving roller according to the site conditions to realize the overall forward and backward movement of the rubber belt , turn on the speed control switch to start the motor, place the large pieces of gangue to be crushed on the initial belt and drop them into the crusher. After the position, open the hydraulic push column to push the tamping plate forward to tamp the gangue pile. The forward and backward movement of the front moving drum and the rear moving drum interacts with the overall movement of the base and steel frame driven by the crawler to complete the overall filling of ...

Abstract

The invention discloses a mine underground gangue transportation, crushing and filling method, mainly comprising: adjusting expansion rack fastening nuts and rear moving drum bearing block nuts according to field conditions to allow a rubber belt to move back and forth; opening a speed control switch to start a motor; placing large gangue to be crushed onto a start belt, allowing to fall into a secondary crusher, and allowing the gangue crushed by the secondary crusher to enter a feeder; allowing the gangue to fall onto the rubber belt at a set speed and be transported to a filling region; after conveying the gangue to specified position of the filling region, opening a hydraulic push post to push a tamping plate to forwardly tamp the gangue pile; moving back and forth the front and rear moving drums and driving, through a track unit, a base and a steel frame to move as a whole in alternate manner, so that overall filling of the filling region is finished. The method herein has the advantages that, for instance, operation is easy, and steps are reasonable; the problem that the belts are complex to detach is solved; moving frequency of equipment is decreased; filling cost is reduced; working efficiency is improved.

Description

technical field [0001] The invention relates to an integrated method of gangue transportation-crushing-filling in mines. It is a self-designed method of using a self-designed multi-functional and fast underground gangue crushing and roadway filling mechanized device placed in the filling area for actual operation. It is specifically designed for mining transportation. How to use filling equipment. Background technique [0002] In coal mining, with the output of coal, a large amount of gangue will be produced. It is difficult to transport gangue underground, and the cost of raising the shaft is relatively high. In addition, after the gangue is raised into the shaft, it will form a gangue hill that occupies a large area and is seriously polluted. The gain outweighs the gain. The gangue is used in the way that the gangue is directly crushed and filled without going up the well. However, with the continuous filling of gangue, the gangue conveying device needs to be continuously...
